y T all whom t may concern 'Be it known thatiI, ALEXNDREiWAGA-l;

Nori, a subject of the Emperor of Russia,

' residing at Kamennoostrowski Perspective,

houseV 24, Petrograd, Russia, have invented certain new and usefulImprovements 1n the Treatment of the Bast of the Linden yor n `warp have but a very small length.

' to the adjacent ends of the strips on both rIhe object of this invention is to pro- -duce from the bast ofthe linden or limetree and the willow long threads which may be used on a loom in the ordinary Way for the manufacture of webs of various kinds. To that effect the films of bast or inner bark of the said trees, separated from the outer bark, are boiledin an open or tightly closed vessel with an alkaline liquid to make the same soft and capable to be subdivided in the longitudinal direction. The concentration of the alkaline liquid andthe duration of the said boiling process depend upon the origin of the bast. The bast received from an old tree f. i. must be boiled a longer time than that from a young tree. If the boiling is effected in an open receptacle the same takes about two hours. The bast films softened in the manner just described are then placed upona table end-byend and cemented together using pasted paper strips or the like, which are sticked or only on the one side. The long bast-film thus produced is then subdivided, by means of appropriate devices, into long narrow vstrips or flat threads which are thenspooled and finally used on looms in the ordinary rIYhe dividing of the bast-films into flat threads may be attained f. i. by passing the films between a flat and a ribbed cylinder .or by means of edged rotating disks.

If it is desired to produce from the bast finewebs,the bastffilms are submitted,rafter etheriirst boiling, to a second boiling process effected during 15-30. minutes within av closed vessel containing a 2%-3% liquid of soluble glass with a view to-receive a fibrousy material which can be without any difficulor THE.

ties decomposed into primary fibrils and then spun to threads either separately 0r lin combination with fibrils of` another origin, as f. i. hemp, line, etc. Such fibrils of another origin may be also brought into the webs produced from the flat or spun threads y of bast by using the threads of bast and the threads fromv another fibrous material con- ]ointly and alternately in separate shuttles of one and the same loom. In such way webs of very various qualities may be man-k*`- ufactured, which webs or textures maybe submitted to all the known treatments with a .view to changethe aspect or color of their surface or to render same Waterproof. What I claim is:

l.' Improvements in the treatment ofthe Y bast of the linden or lime-tree and willow forY the manufacture of webs, consisting in boiling the l`bast separated from the outer bar within an alkaline liquid, cementing together the ends of the separate short bastv films to form a long film, subdividing the latter into strips or flat threads, spooling the said` stripsor threads and utilizing the saine in the shuttles of ordinary looms.

2. Improvements in the treatment of the bast yof the `linden or limetreeand willow for the manufacture of webs, consisting in boiling the bast in an alkaline liquid, slibmitting the same to a second boiling process containingv a 2%-3% liquid of soluble glass, subdividingA the softened bast into elementary fibrils, spinning threads from said fibrils and yusing the threads on looms in the boiling the bast within an alkaline liquid, submitting the same to a second boiling during 15-30 minutes within a closed vesselv l' process during 15-30 minutes within a closed vessel containing a 2%-3% liquid of soluble glass, subdividing the softened bast into elementary fibrils, spinning threads from said fibrils miXedor combined withV fibrils ofanother origin and using the threads for the manufacture of `webs in the ordinary way.
